STANK ASS COOCH HELP

Ok, so am very young, and when I was in 3rd grade I told my mom I had a yeast infection and she thought she got rid of it. So uh... she didnt. I am in 7th grade and im worried. It stinks. I tried baking soda baths. Please help! I cant tell my mom she doesn't listen

Edit: I will find someone else to take me to a FEMALE DOCTOR and get medicine. If she isn't female than I wont be able to trust her. I know, stereotypical, teen girl afraid to say something that could be solved by now
